摘要:
An authentication associated suite discovery and negotiation method for ultra wide band network. The method includes the following steps of: 1) adding a pairwise temporal key PTK establishment IE and a group temporal key GTK distribution IE in an information element IE list of an initiator and a responder, and setting a corresponding information element identifier ID, and 2) an authentication associated process based on the authentication associated suite discovery and negotiation method. The authentication associated suite discovery and negotiation method for ultra wide band network provided by the present invention can provide the discovery and negotiation functions of a security solution to the network so as to satisfy all kinds of application requirements better when multiple pairwise temporal key PTK establishing plans or multiple group temporal key GTK distributing plans co-exist.

The present invention provides a method for protecting the first message of a security protocol and the method includes the following steps: 1) initialization step; 2) the initiating side sends the first message; 3) the responding side receives the first message. The method for protecting the first message of the security protocol provided by the present invention can implement that: 1) Pre-Shared Master Key (PSMK), which is shared by the initiating side and responding side, and the security parameter in the first message are bound by using computation function of Message Integrality Code (MIC) or Message Authentication Code (MAC), and thus the fabrication attack of the first message in the security protocol is avoided effectively; 2) during computing the MIC or MAC of the first message, only PSMK and the security parameter of the first message are selected to be computed, and thus the computation load of the initiating side and the responding side is effectively reduced and the computation resource is saved.

The present invention discloses a multicast key negotiation method suitable for group calling system and a system thereof. The method includes that: a user terminal (UT) negotiates about a unicast key with a base station (BS), derives an information encryption key and an integrity verifying key according to the unicast key, and registers a service group identifier that the UT belongs to at the BS; the BS notifies the UT the multicast key of the service group that the UT needs to apply, constructs a multicast key notification packet, and sends it to the UT; after receiving the multicast key notification packet sent by the BS, the UT obtains the multicast key of the service group that the UT needs to apply by decrypting a service group key application list, constructs a multicast key confirmation packet, and sends it to the BS; the BS confirms that the multicast key of the UT service group is built successfully according to the multicast key confirmation packet sent by the UT.

摘要:
A method and a system for entity authentication in a resource-limited network are provided by the present invention. Said method comprises the following steps: 1) entity A sends an authentication request message to entity B; 2) after receiving the authentication request message, entity B sends an authentication response message to entity A; and 3) entity A determines the validity of entity B according to the received authentication response message. The authentication between entities in a resource-limited network can be implemented by the application of the present invention.

The present invention discloses novel uses of specific menthol-derivative compounds of Formula 1, and compositions thereof, for methods of providing oral and systemic health care benefits, and methods of up-regulating or down-regulating periodontal disease metabolites: Formula 1 wherein, X is an oxygen atom or an NH radical; and R is an unsubstituted or substituted aryl or aliphatic radical. In some embodiments, the oral and systemic health care benefits include biofilm anti-attachment, anti-inflammation, anti-oxidant, anti-bone loss, and anti-microbial benefits. In some embodiments, the periodontal disease metabolites correspond to healthy and/or diseased oral status and allow differential diagnosis of oral health.
